Patois

Look up patois in Wiktionary, the free dictionary.

Patois (/ˈpætwɑː/, pl. same or /ˈpætwɑːz/)^[1] is speech or language that is considered nonstandard, although the term is not formally defined in linguistics. As such, patois can refer to pidgins, creoles, dialects or vernaculars, but not commonly to jargon or slang, which are vocabulary-based forms of cant.

In colloquial usage of the term, especially in France, class distinctions are implied by the very meaning of the term, since in French, patois refers to any sociolect associated with uneducated rural classes, in contrast with the dominant prestige language (Standard French) spoken by the middle and high classes of cities or as used in literature and formal settings (the "acrolect"). Sociolinguistics is the discipline that studies the relationship between these language varieties, how they relate to the dominant culture and, in the case of France, to national language policy.
